Effect of splenectomy on platelet activation and decompression sickness outcome in a rat model of decompression

- Article scientifique
Article scientifique
Introduction: Splenic platelets have been recognized to have a greater prothrombotic potential than others platelets. We studied whether platelets released by splenic contraction could influence the severity and outcome of decompression sickness (DCS) and bubble-induced platelet activation.
Methods: Sixteen, male Sprague-Dawley rats were randomly assigned to either a control or a splenectomized ...
Mechanism of action of antiplatelet drugs on decompression sickness in rats: a protective effect of anti-GPIIbIIIa therapy

Article scientifique
Literature highlights the involvement of disseminated thrombosis in the pathophysiology of decompression sickness (DCS). We examined the effect of several antithrombotic treatments targeting various pathways on DCS outcome: acetyl salicylate, prasugrel, abciximab, and enoxaparin. Rats were randomly assigned to six groups. Groups 1 and 2 were a control nondiving group (C; n = 10) and a control diving ...
Flying after diving: should recommendations be reviewed? In-flight echocardiographic study in bubble-prone and bubble-resistant divers

- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
INTRODUCTION: Inert gas accumulated after multiple recreational dives can generate tissue supersaturation and bubble formation when ambient pressure decreases. We hypothesized that this could happen even if divers respected the currently recommended 24-hour pre-flight surface interval (PFSI). METHODS: We performed transthoracic echocardiography (TTE) on a group of 56 healthy scuba divers (39 male, ...
Decompression induced bubble dynamics on ex vivo fat and muscle tissue surfaces with a new experimental set up
04 avril 2015,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Vascular gas bubbles are routinely observed after scuba dives using ultrasound imaging, however the precise formation mechanism and site of these bubbles are still debated and growth from decompression in vivo has not been extensively studied, due in part to imaging difficulties. An experimental set-up was developed for optical recording of bubble growth and density on tissue surface area during ...
Cutis Marmorata skin decompression sickness is a manifestation of brainstem bubble embolization, not of local skin bubbles
10 avril 2015,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
"Cutis Marmorata" skin symptoms after diving, most frequently in the form of an itching or painful cutaneous red-bluish discoloration are commonly regarded as a mild form of decompression sickness (DCS), and treated with oxygen inhalation without reverting to hyperbaric recompression treatment. It has been observed that the occurrence of Cutis Marmorata is frequently associated with the presence of ...

Le monde sous-marin est devenu accessible au plus grand nombre. Les méthodes de plongée se sont diversifiées, la population de plongeurs aussi... Mais la plongée demeure une activité à risques. Les pathologies cardiaques peuvent faire courir des dangers importants, non seulement au plongeur, mais aussi à tous ceux impliqués en cas d'assistance. Or, les données concernant les décès en plongée mettent ...
Influence of decompression sickness on vasocontraction of isolated rat vessels
18 février 2015,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Studies conducted in divers indicate that endothelium function is impaired following a dive even without decompression sickness (DCS). Our previous experiment conducted on rat isolated vessels showed no differences in endothelium-dependent vasodilation after a simulated dive even in the presence of DCS, while contractile response to phenylephrine was progressively impaired with increased decompression ...
Fluoxetine Protection in Decompression Sickness in Mice is Enhanced by Blocking TREK-1 Potassium Channel with the "spadin" Antidepressant
16 février 2016,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
In mice, disseminated coagulation, inflammation, and ischemia induce neurological damage that can lead to death. These symptoms result from circulating bubbles generated by a pathogenic decompression. Acute fluoxetine treatment or the presence of the TREK-1 potassium channel increases the survival rate when mice are subjected to an experimental dive/decompression protocol. This is a paradox because ...
